CNC Laser: Precise Cutting and Engraving of "The One Ring" inscriptions // Popular STEM // Bella Baxter

in Popular STEMyesterday

Greetings, travelers!

After some time, today I come to talk about one of my favourtie processes in the realm of Digital Fabrication: CNC (Computer Numerical Control) Laser cutting and engraving have transformed the way we approach design and manufacturing. I have recently reflected on a project I completed some time ago, a piece crafted using Laser. The piece is the top part of a bigger box, that I can show in a different post, having a central cut out circle with the iconic inscriptions from "The One Ring" engraved around it, ij elvish like in the movies.

The CNC Laser technology involves the use of a computer-controlled machine head, accoplied to two rails in both axis that move it vertically and horizontally in the table, reflecting the enormous laser generated generaly on the back portion of the machine, and then sent to its final focus point through mirrors disposed in different ways tridimensionaly, but always making 90degree angles through them. It can then precisely cut or engrave materials based on digital designs.

The process begins with creating a detailed model using CAD (Computer-Aided Design) software. This digital blueprint guides the laser's movements, allowing for intricate patterns and precise cuts that would be difficult to achieve by hand. The laser's parameters, such as power, speed, and focus, are carefully adjusted according to the material being used to ensure accuracy and quality. After the cutting and engraving were completed, the piece underwent a finishing process to enhance its appearance and longevity. I employed sanding, to smooth out any rough edges and remove residue from the laser work, followed by the application of varnish, which not only protects the wood but also brought out the contrast between the engraved text and the natural tones of the MDF. The varnish added a subtle sheen, giving the piece a polished and professional look. I am still finishing out the last process I wanted to apply years later: tracing the engraving with a black pen. At that point of the process, today, my dear cat Bella Baxter decided it was the perfect spot to relax. She gracefully settled on top of the piece, and I smiled.

I like to smile, and I hope this post introducing the potential of CNC Laser processes (or Bella's attempt to get the photographer's attention) made you smile, too. Do you have any particular curiosity or interest for a Digital Fabrication, CNC and/or CAD information? Tell me about it in the comments bellow! Cheers :)
